Concordance
Thematic: Full thematic concordance. The stamp depicts the Freiburger Münster (Freiburg Minster), and the postcard features a panoramic view of the same monument. Both elements focus exclusively on the same Gothic architectural landmark in the city of Freiburg im Breisgau, creating perfect visual and thematic harmony.
Geographic: Perfect geographic concordance. The stamp was issued specifically for the Baden region (French Occupation Zone), the postmark was applied in Freiburg (the city where the cathedral is located), and the postcard illustrates the cathedral itself and the Freiburg cityscape. There is total geographic alignment between the issuer, the place of cancellation, and the subject.
Temporal: Strong temporal concordance. The postmark is dated June 5, 1948. This period is highly significant as it predates the West German monetary reform of June 20, 1948, by only a few days. Using the 1 Mark stamp during its original validity, with a cancellation from the subject city during the occupation period, establishes an authentic and historically valuable temporal concordance.
